Lunar Roll Maneuver (-13.6384 degrees)
2021/062 07:24:32 ATC MOD_OA04_NIGHT_RATE.1 (1:53 early, in addition to 02:58 delta time due to implementation of 40/60 BAP, total shift of 4:51 early)

2021/062 08:20:33 ATC MOD_OA03_DAY_RATE.2 (1:53 late, in addition to 00:00 delta time due to implementation of 40/60 BAP, total shift of 01:53 late)
Terra Lunar Roll will take place on 2021/062.
General Instrument Comments:
MODIS is in Science Mode, using all A-side components, but
cross-strapped to Formatter B, with the blackbody nominally maintained at 290K and
the Solar Diffuser Door at the Screened position.
Note that the BlackBody will be maintained at 285K.
Note that STS File scheduling was implemented on 2020/313. The STS Files create alternating orbits allowing for coverage of the poles and lengthen Night Rate collection by 00:05:56 each orbit.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
Non-MODIS Significant Events:

records) can be found at the following URL. Note that a password is now
required to access the EOS mission links web pages. There are directions
